Hi everyone,
Has anyone used the Seeed WM1302 with a Raspberry Pi 5 running ChirpStack Gateway OS?
I’m specifically trying to confirm two things:
Does it work correctly on the Pi 5 with Gateway OS?
Is the installation process the same as on the Raspberry Pi 4, or does the Pi 5 require any additional steps (SPI configuration, GPIO differences, drivers, etc.)?
Any feedback or experience would be greatly appreciated.
Thanks in advance!
Not only the Raspberry Pi 5, any ARM/Linux system can drive the SX1302.
As shown in the figure above, connect the 7 pins of the SX1302 to the MCU.

Yes, this module should work using the ChirpStack Gateway OS installation steps for Raspberry Pi.
Thank you very much for your reply.

ERROR: Failed to set SX1250_0 in STANDBY_RC mode

I followed the Seeedstudio WM 1302 Wiki.
I could not even set it up on Chirpstack after that error. Copilot suggested the SPI is not starting as WM1302 only works with Pi 4B.
Just heads up, this is my first project.
Let me know your thoughts.
Cheers
